Slacko is a series of Puppy releases (5.3x to 5.4 with the code name Slacko), uses the latest Puppy Woof 2 build code, programs and scripts. It has high Slackware binary software packages compatibility (hence is a Spup). It was created by the lead developer Micko and the community. Including months of testing, upgrades and updates. Includes hardware recognition, programs and scripts unique to Puppy. (Not to be confused with Barry's Precise Puppy 5.4x).

Slickpet is a cut down version of Quickpet to get a few handy apps without diving into the well stocked Puppy Package manager. Slickpet also supports installing SFS packages, which are modules that are loadable as layers in the Puppy filesystem. Packages such as Libreoffice-3.5.3, JRE and Samba3.5.4 are available.
While on the Puppy Package Manager, apart from Puppy's native PET package format it can also fetch Slackware, Salix and Slacky packages in tgz or txz format.
Puppy's sfs format is supported by a program called sfs_load. Sfs are a way to load layered filesystems so that the filesystems can be unioned and act as one. Read more.
Slacko has Abiword and Gnumeric, late versions to open those documents and spreadsheets to keep you working.
Lots of types of multimedia are supported so you can play hard.
Slacko is aimed at reasonably modern machines up to six or seven years old. It may run on even older hardware.
Much work has gone into fine tuning packages such as Samba and the light weight alternative Samba-TNG. There is also a netboot add on that allows you to boot Puppy over your LAN.

Slacko Puppy 5.3.3 offers something for everyone, whether for work or play, all in under 115 megabytes!
